. BATTERY TERMINAL.

' Application Be it known that I, WILLIAM Bonn-i notions, a citizen ofthe United States, re- 2 siding at Junction City, in the county ofcertain new and useful Improvements in Battery Terminals; and I dodeclare the following to be a full, clear, and exact dcscript-ten of theinventiomsuch as will-enable others skilled in the art to which it ap- 1tion.

I secondary socketed member over the binding binding post use the same,refer- "pertains .to make and accompanying drawence being had to theings, and to the figures thereon, which form a part of this specifica-This invention relates to a terminal for batteries and the primaryobject thereof is to provide a terminal fastening for the cable so thatthe cable can be secured 20 to the binding post in such a manner that iti may be disconnected without danger of breaking the battery cell.

. Ordinarily connections are made between the cable. and the bindingpost by placing a post and fastening it in place bya set screw. After awhile the socket and binding post freeze or stick together on account ofcorrosion which sets up between the socket and the or be members of tarthe connection, Then in 9 er to disconnect the cable from the bindmgpost, the binding post is put under severe strain resulting in its beingbroken oil, in many instances, so that a new binding post has to beburned on.

desired result battery y invention contemplates the elimination of theabove mentioned difiiculty and the is accomplished by novel means'whichwill be s ecifica'lly referred to hereinafter, reference eing had to theaccompanyi-ng drawings, in which 'Fig. 1 is a perspective view of abattery terminal constructed in accordance with my invention.

Fig. 2 is a sectional view through the terminal showing the parts inposition for making the connection.

Fig. 3 is a similar view showing the complementary members disconnected,and

Fig. 4 is a sectional view through the socket member and a securing nutfor fastening it to the binding post.

The battery 1 may be of approved construction with a bindingpost 2 inthe form of a truncated cone with an and State of Kansas,-have invented'out of the binding '5 carried by the soc .internal conical socket onrecess of reference marked ner.

upstanding threaded stud 3 pro ecting above the truncated portion of theinding post. For c0nvemence, I may utilize a bolt with ahead 4 a cast inthe binding post asclearly illustrated in'Fig. 2. The head 4; serves asan anchor to prevent the studrrom being pulled et member 6.

The socket member: is provided with an 7 dapted ost bythe adjusting nut]to tightly fit over thelbinding 01st 2 and'it' isprovided withtashouldere portion or seat 8 to receive the flange 9 of the nut 5 havin apolygonal portion 11 so, that it may e received between the jaws of awrench." 'llhe'flange is held cover plate 12 fastened to thesocket-member 6 or thesocket member can be loosely secured to the nut inany well known manadapted to have rotative movement with respect to thesocket member, therefore when the on the stud 3, the socket forced downon the binding post to make electrical connection between thecomplementary fastened When it is desired to disconnect the com;lementary members 2 and'G, a wrench may e applied to the polygonalportion 11 of the nut 5, which ert. a straight et member so 6 are stucktogether by corrosion, the force will be sufficient-to pull them apartbecause the nut and stud will act as a" screwjack exerting great powerand since the strain will be on the stud and on the binding post V 2, nostrain will be communicated to the nut 15 screwed member will be on itsseat by a members 211ml 6, the cable 14' bein to the socket member inthe usua upbn'belng' unscrewed will ek- A longitudinal pull on thesockthat even if the members 2 and cell, 'consequentlyliability of thecell becoming broken will be entirely eliminated.

I It will be apparent from the foregoing that the connection between thecable an the binding post may be made and broken m a very convenient andexpeditious manner and that liability of disruption of the battery jaror cell in making and breaking the connection will beentirelyeliminated. What I claim and desire to secure by Letters Patentis:
